MACHINE, FOR TREATING TOBACCO.

SPECIFICATION forming part of Letters Patent No. oaaoe, dated June as, 1898.

Application filed June 20, 1896;

improvement and then point out the novel features in the claims.

In the accompanying drawings, Figure 1 is V a side view of a machineembodying my im- Fig. 2 is a plan of the same, certain parts at the delivery end being omitted. Fig. 3 is a central longitudinal section.

Similar letters of reference designate corresponding parts in all the figures.

A designates a tank, which may be made of any suitable material and form. Most advantageously it may be made of rectangular form and erected upon a frameworksuch, for example, as the framework B. It has an inclined bottom section a. Liquid as it is ordinarily used for treating tobacco will be kept in the tank up to a suitable level. LiQ- uid may be supplied by any suitable means, preferably under automatic regulation.

Leaves or pieces of tobacco are introduced at one end and are moved forward to the delivery end by means of reciprocating bars O C D D. The reciprocating bars O 'O have on their lower edges teeth 0 somewhat resembling ordinary saw-teeth, although madeless sharp at the points. The bars D D have corresponding teeth cl, but they are located on the upper edges. It will be observed that the teeth a of the bars 0 C have their points arranged in the direction of the delivery end of the tank, and that this is also true of the teeth d of the bars D D.

The bars 0 C have upwardly-extending arms 0' o which are connected to cross-bars 0 0 From these cross-bars extend upwardly arms 0 c, that are fi tted'to eccentrics 0 O mounted upon shafts C C. These shafts are journalecl in. bearings 0 arranged beyond the sides of the tank and affixed to a framework-E.

The eccentrics O O on the shaft 0 are set reversely and so are the eccentrics (1 G on the shaft 0 the eccentrics O on the two Serial No. 596,255. (No model.)

shafts O G being set alike and the eccentrics O on said shafts being also set alike.

Onthe shafts O 0 are cranks G those on one side of the machine being at right angles to those on the opposite side, being connected by rods: 0 v Onthe shaft 0 is a gear 0 By rotating the gear a both shafts O G will be rotated, and thus the eccentrics C G will be rotated. Thus the two sets of bars 0 G will bemoved downward and at the same time toward thedelivery end of the tank A, then upward,- and, while elevated, back to the starting position. The motions of each of the two sets of bars ,O C are always the reverse of those of. the other series. Hence these two series of bars alternate in their movements toward the delivery end of the tank A.

[The bars D D are provided with arms d 01 which are fastened to cross-bars d d. The cross-bars d d are fastened to bars d d. The bars (1 d are connected by cross-bars d (1 and from these extend upwardly arms d 01 toeccentrics D D affixed to shafts D D These shafts D D are mounted in bearings d, affixed to the framework E, and arranged wholly beyond the sides of the tank. The eccentrics D D of the shaft D are set reversely, and so are the eccentrics D D of the shaft'D. Hence when the said shafts and'eccentrics rotate each of the series of bars D D -will move reversely to the other and each-will have a motion upward and forward toward the delivery end of the tank and then downward and rearward to the starting position, themovements of each of the two series of bars being the reverse of those of forced downward within the liquid in the tank and moved forward until they reach the two series of bars D D, when they will be moved upward and forward until they are withdrawn from the liquid in the tank and delivered entirely from the tank. One of the series of bars C Oas, for example, the series of bars Cwill be provided with upturned portions c whereby a board 0 will be supported across the tank A. This will preclude leaves of tobacco from passing toward the delivery end'of the tank above the bars 0 O.

Preferably the rear ends of the bars 0 G will be inclined to facilitate moving the leaves of tobacco downward to the under side of the main portions of the bars.

Obviously the bars 0 C will not only move the tobacco forward, but will also agitate it, so that it may be thoroughly subjected to the liquid in the tank and will soak up the same. Equally efficacions will the bars D D be for shaking the tobacco-leaves as they are moved from the liquid for the purpose of facilitating the draining off of the superfluous liquid.

At the delivery end of the tank I have shown rollers F F which will receive the ,tobacco and carry it forward to a suitable receptacle. These rollers may be driven in any suitable manner.

With the rollers F F are preferably combined two sets of fingers G G affixed to rockshafts Gr G mounted in bearings supported in a suitable framework. To these rockshafts are affixed crank-arms g 9 Rods g g extend from these crank-arms g g to a crank carried by a rotary shaft G, which is journaled in a suitable framework and driven by any suitablemeans.

The fingers G G2 are curved and their forward extremities are capable of projecting quite close to the meeting surface of the rollers F F They vibrate toward and away from this space and alternate with each other in the forward movements. They aid in delivering the tobacco to the rollers and prevent clogging.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination with a tank, of two series of horizontal parallel bars having downwardly-projecting teeth and operating above and entirely clear of the bottom of the tank, the bars of one series alternating with those of the other series, means comprising two sets of reversely-set eccentrics, one set at each end of said bars, and connections between said bars and eccentrics for moving'the two series of bars in reverse order, downwardly, forwardly, upwardly and rearwardly, substantially as specified.

2. The combination with a tank, of two series of horizontal parallel bars having downwardly-projecting teeth and operating above and entirely clear of the bottom of the tank, the bars of one series alternating with those of the other series, means comprising two sets of reversely-set eccentrics respectively arranged at opposite ends of said bars, for moving the two series in reverse order, downwardly, forwardly, upwardly and rearwardly, and cranks and a connecting-rod for causing the two sets of eccentrics to move in unison, substantially as specified.

3. The combination with a tank having a horizontal bottom section, and an upwardlyinclined bottom section, of two sets of toothed bars, one set having teeth on the lower side and overlying and being parallel with said horizontal section and operating above and clear thereof, and the other set having teeth on the upper side and overlying and being parallel with said inclined section, and means for reciprocating said sets of bars, substantially as specified.

4:. The combination with a tank having a bottom provided with a'horizontal section,

and an upwardly-inclined section, of two sets of toothed bars respectively above and lying parallel with said bottom sections, the teeth of the horizontal bars projecting downwardly and those of the inclined bars projecting upwardly, and means for simultaneously reciprocating said sets of bars, substantially as specified;

5. The combination with a tank having a bottom provided with a horizontal section, and an upwardly-inclined section at its delivery end, of two sets of bars, one set having teeth on the lower side and arranged above and parallel with said horizontal bottom sec tion, and the other set having teeth on the upper side and arranged above and parallel with said inclined bottom section,and each set of bars comprising two series of alternatelyarranged bars, reversely-set eccentrics at opposite ends of said bars, and connections between said eccentrics and series of bars for simultaneously moving the series of each set'in opposite directions,substantially 'as specified.

6. The combination with a tank, of bars, roughened or toothed on their upper surfaces and extended upwardly out of the tank at the delivery end, means for reciprocating said bars, rollers adjacent to the upper end of said bars, and fingersoscillating opposite the said rollers, substantially as specified.

7. The combination with a tank, of bars, roughened or toothed on their upper surfaces and extended upwardly out of the tank at the delivery end, means for reciprocating said bars, rollers adjacent to the upper end of said bars, and two sets of fihgers oscillating opposite the said rollers, substantially as specified.

8. The combination with a tank, of horizontal bars roughened or toothed on their under edges, and provided at their infeed ends with upwardly-inclined sections likewise roughened or toothed, substantially as specified.

9. The combination with a tank, of bars, roughened or toothed on their under edges, a stop board or piece attached to such bars, and means for moving the bars downwardly, forwardly, upwardly and rearwardly, substantially as specified.

10. The combination with a tank,of horizontal bars roughened or toothed on their under 606,209 Q y a tal parallel bars roughened or toothed on their lower sides and operating above and entirely clear of the bottom of the tank, means for moving said bars downwardly, forwardly, up-

wardly and rearwardly, shafts supporting said means, bearings for said shafts, and sups ports for said bearings independent of and beyond the sides of the tank, substantially- 15 as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
